Using channel 14 for wireless for personal wireless network

It is impossible for the users using wireless networks at their home to use channel 14 in the SSIDer, due to the strict laws of radio spectrum. According to the laws of radio spectrum it is essential that a user and companies follows the radio Spectrum regulation to ensure the coexistence of all the services without interference and ensure legal and efficient use of wireless network. Internationally, the use of spectrum is regulated through the ITU Radio Regulations and by the decisions of international bodies like the European Conference of Postal and Telecommunications Administrations (CEPT) and the EU. Nationally, the responsibility for managing the use of spectrum and licensing is over the Ministry of Industry, Tourism and Trade through the Ministry of Telecommunications and Information Society (SETSI), being provided by law the creation of an Agency of the radio spectrum. In the CMT, which were required only to inform the regulatory provisions on spectrum and of the specifications governing the tender procedures for granting concessions for use, with particular emphasis on aspects affecting electronic communications markets?

Under EU law, the spectrum is a public good that is exploited by three uses: ordinary, special and exclusive. No license but with restrictions, without causing interference and unprotected. In some areas the allocation of frequencies for a particular service requires a license and some bands were obtained by tender those dedicated to mobile: 900 MHz, 1800 Mhz, 2, 1 GHz and access Wireless (Wack et.al, 2002). It is the responsibility of all the EU states to ensure that the tables of national radio frequency allocation and information on rights, conditions, procedures, charges and fees concerning the use of spectrum be made available to the public. However, the information covered by the obligation of professional secrecy, in particular information about undertakings, their business relations or their cost components should not be disclosed.

Reasons behind the unavailability of 600Mbps 802.11n APs

802.11n 600 Mbps makes simultaneous use of the bands 2.4 GHz and 5.4 GHz, while the earlier B and G only use 2.4 GHz. This is advantageous since the 2.4 GHz band is heavily congested due to the success of wireless technology in general. The frequency of 5.4 GHz airwaves Use a cleaner and free of interference from other networks. Following are some of the reason of the unavailability of the 600Mbps 802.11n APs;

Higher prices

The biggest technology represents a higher cost in the final products that use MIMO. Note that prices should suffer a drop after some time, with the popularization of technology and increased demand and competition;

Compatibility issues

This disadvantage has more to do with the fact that there are many products on the market ready for 802.11n and the default 'n' has not been certified. It is possible that, until final certification of this standard, the most significant changes occur and the current products are not compatible after these modifications.

Low speed

The other big drawback (basically take away the candy ...
